Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] In the embodiment of the present invention, the system allocates independent memory space for each display interface and display window. Below we will refer to the above-mentioned display interface and display window as windows, and the test equipment will initialize the window when it is turned on. , the main task of initialization is to assign values ​​to each attribute of the window and open up memory space for the message pool. The properties of the window include: window memory pointer, window layer number, window position, window width and window height, etc.

[0024] The test device of this embodiment saves the corresponding window display messages in order according to the multiple key value information input, and displays multiple windows accordingly, with two process steps:

[0025] refer to figure 2 , the first process step is to seq...

Abstract

The invention provides a multi-window display method of a test device. According to various input key value information and the current state, the test device analyzes window display information, sequentially stores corresponding window display information, and displays multiple windows according to the corresponding window display information. The multi-window display method comprises two process steps: a first process step, sequentially obtaining window display information from the stored window display information and displaying corresponding windows according to the obtained window display information; and a second process step, obtaining sensitivity to the key value information, firstly hanging up the first process step, and then sequentially storing the window display information corresponding to the key value information. The multi-window display method reduces unnecessary refreshing on windows, saves time and resources, refreshes the windows which have changes, and does not refresh the windows which do not have changes. The windows are refreshed according to the order of the key information so that the refreshing is timely and efficient, and refreshing chaos does not happen.

Description

technical field [0001] The invention relates to the field of electric variable testing, in particular to a multi-window display method of testing equipment. Background technique [0002] With the development of digital technology, the functions and indicators of various digital test equipment are also increasing and improving. Therefore, the functions of digital test equipment are becoming more and more diverse. With the increase of functions, the display interface of the test equipment There are more and more contents, so there are many display windows on the display interface of the test equipment, and these display windows are constantly refreshed by receiving the key presses of the test equipment. The traditional test equipment refresh management method for the display interface with multiple display windows is as follows: Since the graphics card of the test equipment itself has 5 memory spaces, these 5 memory spaces are allocated to different 5 display layers, each disp...
